1. Confidence in Software Cost Estimation Results based on MMRE and PRED Presentation for PROMISE 2008 Marcel Korte [email_address] Dan Port University of Hawai'i at Manoa Phone: +1-(808)-956-7494 [email_address]
10. Bootstrapped MMRE intervals 2/2 13 May 2008 NASA93 dataset Desharnais dataset (*note only D & F used with FP raw and FP adj)
11. Accounting for Standard Error 13 May 2008 Model ranking based on MMRE, not accounting for Standard Error. Model ranking based on MMRE, accounting for Standard Error at 95% confidence level. COCOMO81 COCOMONASA NASA93 1. A A A 2. E E E 3. C C C 4. B D B 5. D B D COCOMO81 COCOMONASA NASA93 1. A A A, B, C, D, E 2. C, E E - 3. B, D B, C, D - 4. - - - 5. - - -
12. How much confidence needed? 13 May 2008 Bootstrapped PRED(.30) intervals with significant differences (32%-confidence level, COCOMONASA dataset)* *This a very crude example. There are more refined approaches that account for simultaneous (ANOVA like) comparisons Bootstrapped PRED(.30) intervals (COCOMONASA dataset)
